myenergi - eddi relay & sensor board

  • "Just had my zappi installed last week and am absolutely delighted with the system.
    It is simplicity itself to switch through the charging modes and the graphics showing where the power is coming from and going are very well depicted on a very clear backlit screen.
    Also the unit looks very neat and appropriate on the front of the house and doesn’t have the slightly “industrial” appearance of some of the other systems I have seen.
    My communications throughout with MyEnergi and the installer were excellent. I would highly recommend."

    "I have got my zappi unit installed yesterday and I am so delighted with it. It works a charm and providing tons of information on screen. I only went for the unit becuase of its ability to use Solar power to charge the car without sending it to the grid but having used the zappi unit and reading about its features I am absolutely delighted with my choice. I can’t wait to see the mobile App in the development to come out. Keep your good work going. Highly recommend it to anyone who is looking for a home charger for theeir EV. Thank you"
